when i turn on my heat or defroster hot air blows on pass side but drv side only ever blows cold air. plz help

 

Check and see if the actuator valves are working on the air transfer system..you will need to look up under the dash on the drivers side..and likely remove the Right knee moldings around the head unit to see it....

Apparently it's a common issue....
